NEW YORK (AP) — Hip-hop mogul James Rosemond, who is already jailed on federal drug-trafficking charges, has been indicted on gun charges.

The New York Post reports that prosecutors unveiled a revised indictment Friday accusing Rosemond of possessing a submachine gun and a silencer.

The 46-year-old CEO of New York-based Czar Entertainment was arrested in June on charges of running a criminal enterprise between New York City and Los Angeles that shipped cocaine in music equipment cases.

Officials say the weapons were seized during searches of Rosemond’s properties.

Under federal law, possession of a machine gun or firearms silencer in connection with a drug crime carries a mandatory minimum sentence of 30 years in prison.
